Answer:
Step-by-step explanation:
Jerry charges $15 for each lawn that he cuts. He can cut at most 10 lawns because of his limited time which is due to chores and homework. This means that if he is able to cut lawns, he would be making 10×15 = $150. This is the maximum that he can make. Also, Jerry has determined his fixed cost to be $10 a week. Therefore, his maximum profit will be
150 - 10= $140
This is modelled by the function below
y = 15x − 10
Where y(profit) depends on x(number of lawns).
The domain of this function is the set of all possible values of x for which the function is defined.
The domain of the function is ( x lesser than or equal to 10)
Arc WTS is twice the measurement of angle R.
So arc WTS equals 2R
Arc WRS is twice the measurement of Angle T.
So arc WRS equals 2T
The sum of the two arcs WTS and WRS equal 360 degrees,
So now we have 2R + 2T = 360.
Divide all terms by 2:
R + T = 180
The sum of supplementary angles equal 180 degrees, therefore angles T and R are supplementary.
Answer:
4
Step-by-step explanation:
-3(4x+3)+4(6x+1)=43
-12x-9+24x+4=43
12x-5=43
12x=43+5
12x=48
x=48/12
x=4
Answer:
0.9
90%
Step-by-step explanation:
Dividing 10 into 9.0 we get the decimal 0.900.
As a percentage this is 0.900 * 100 = 90%
64, because its square root is 8.
49, because its square root is 7.
144, because its square root is 12.
4, because its square root is 2.
